Inductor and production method thereof

Abstract

The present invention provides a system and method for producing a reliable inductor having an internal conductor with a small electric resistance. A metal wire formed in a nonlinear shape is used as the internal conductor. In an exemplary embodiment of the invention, the internal conductor has a coil-like shape with portions adjacent to each other with respect to the axial direction of the coil being positioned in a substantially cylindrical gap formed in the axial direction of the coil. By providing a gap around the internal conductor, stress between the internal conductor and a ceramic material surrounding the conductor can be eliminated. As a result, the characteristic deterioration or crack generation in the inductor chip is eliminated. Moreover, the leakage flux among the coil pitches of the conductor is reduced, thereby improving the characteristics of the inductor.
